This report provides a detailed review of the taxation of household savings in 40 OECD and partner countries. It examines the different approaches that countries take to taxing household savings, and calculates marginal effective tax rates on a wide range of savings vehicles (including bank accounts, bonds, shares, private pensions and housing) to assess the impact of these approaches on savings behaviour. It examines asset holdings across income and wealth distributions to help assess the distributional impact of savings taxation, and discusses recent changes in the exchange of information for tax purposes between tax administrations. It also draws out a range of implications from this analysis for savings tax policy as part of an inclusive growth tax agenda.

This report examines the role and design of net wealth taxes in OECD countries. It provides some background on the use of wealth taxes over time in OECD countries as well as on trends in income and wealth inequality. It then assesses the case for and against the use of a net wealth tax to raise revenues and reduce inequality, based on efficiency, equity and tax administration considerations. The effects of personal capital income taxes and taxes on wealth transfers are also discussed to understand how these taxes interact with net wealth taxes. Finally, the report looks at practical tax design issues and shows that the way a wealth tax is designed, which has varied across countries, has a significant impact on the effectiveness and equity of the tax. The report concludes with a number of practical tax policy recommendations regarding wealth taxes.
